Get All The Parts Of The Heart Labeled Background. Along with lymphatic vessels, the blood, blood vessels, and lymph, the heart composes the circulatory system of the body. The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs.
The heart is a muscular organ about the size of a closed fist that functions as the body's circulatory pump. These roadways travel in one direction only, to keep things going where they should. If it stops pumping blood you cannot survive.
The parts of the human heart can be broken down into four chambers, muscular walls, vessels, and a conductive system.
The greatest danger for your heart is a chamber = a part of the heart that is separated from other parts by a thin muscle. The heart pumps blood through our immense and complicated circulatory systems at high pressure. The heart, one of the most significant organs in the human body, is nothing but a muscular pump the human heart and its functions are truly fascinating. One chamber on the right receives blood with waste (from the body) and another chamber pumps it.
